Simple way to construct and remember chords:
In the first part we have seen how the major and minor chords are constructed by using a very simple formula. Now we will see how the other 2 important chords namely diminished & augmented chords are built.
The simple formula which, straight way gives the diminished chord is:
The 3 notes in a diminished traid chord = Root key, 3rd keyfrom root key, 3rd key from the 2nd note.
Diminished chord C: C D# F# (5, 3, 2 finger of left hand)
1st note : C is the first note being the root note for C chord.
2nd note: D# is the 3rd key from C (i.e.C# > D > D#)
3rd note : F# is the 3rd key from D# (i.e. E > F > F#)
Similarly all 12 chords can be calculated and remembered.
However it is more easy to remember by turning major chord into minor, diminished or augmented.
Example: By lowering the 2nd note half step we turn the major chord into a minor chord.
Now how to turn major chord in to diminished chord ?
Major chord : (root note) (2nd note) (3rd note)
Diminished chord: (root note) (lowered by half step) (lowered by half step)
(half step means just one key raised or lowered)
CM : C E G
C dim: C D# F#
The 3 notes in a augmented chord are : Root key, 4th key from root note, 4th key from the 2nd note.
Augmented chord C : C E G#
1st note : C is the root key.
2nd note : E is the 4th key from C (i.e. C# > D > D# > E)
3rd note : G# is the 4th key from E (i.e. F > F# > G > G#)
How to turn major chord into augmented chord?
Major Chord : (root note) (2nd note) (3rd note)
Augmented Chord : (root note) (2nd note) (raised by half step)
CM : C E G
C aug : C E G#
